How to Make a Casserole Perfectly

Tip 4. Make Sure Your Casserole Is the Right Temperature Before Baking It

The beauty of casseroles is that you can freeze them and eat them another day. Unfortunately this can wreak havoc on your casserole if you don’t do it properly. Some folks just throw the casserole in the oven frozen and let it bake for longer, but this can lead to really overcooking your ingredients. Be sure to defrost your casserole completely in the refrigerator before you bake it. This can take up to 2 days. Also, let it come up to room temperature as your oven preheats. If you put a cold casserole in the oven, the outer edge could cook too fast while the middle cooks too slowly.
